SAFETY WARNINGS
G MODIFICATIONS NOT AUTHORIZED BY Konica
Konica copiers are renowned for their high reliability. This reliability is achieved through high-quality design and a solid service network. Photocopier design is a highly complicated and delicate process where numerous mechanical, physical, and electrical aspects have to be taken into consideration, with the aim of arriving at proper tolerances and safety factors. For this reason, unauthorized modifications involve a high risk of degrading performance and safety. Such modifications are therefore strictly prohibited. The points listed below are not exhaustive, but they illustrate the reasoning behind this policy. Prohibited Actions : (1) Using extension cables or a different power cord than specified by Konica. (2) Using other fuses than specified by Konica. Safety will not be assured, leading to a risk of fire and injury. (3) Disabling fuses or bridging fuse terminals with wire, metal clips, solder or similar. (This applies also to thermal fuses.) (4) Removing air filters (except for replacement). (5) Disabling relay functions (such as wedging paper between relay contacts, etc.). (6) Disabling safety functions (interlocks, safety circuits, etc.). Safety will not be assured, leading to a risk of fire and injury. (7) Performing actions to copier not described in the instruction manual or the service handbook. (8) Using parts other than specified by Konica.
G CHECKPOINTS WHEN PERFORMING ON-SITE SERVICE
Konica copiers are extensively tested before shipping, to ensure that all applicable safety standards are met, in order to protect the customer and customer engineer from the risk of injury. However, in daily use, any electrical equipment will be subject to parts wear and eventual failure. In order to maintain safety and reliability, the customer engineer must perform regular safety checks. Caution : (1) Wear clothing that facilitates work and is designed for safety. (2) Carry out all procedures carefully to prevent injury. (3) Be sure to disconnect the power cord of the copier and all optional equipment from the AC outlet. Simply turning off the power switch is not sufficient, because paper feed units or other electrical equipment may be powered also when the power switch is turned off. (4) Proceed with special care when performing operation checks or adjustment while the unit is powered. When carrying out operation checks or adjustment while external covers are removed, the risk of electrical shock exists when touching parts which carry high voltage or electrical charge. The risk of injury exists when touching moving parts such as gears or chains.
C-2 IP-421 PRINT CONTROLLER
Safety and Important Warning Items
The following list is not exhaustive, but it includes actions which must be carried out at every service call. Caution : (1) Check external covers and the frame for sharp edges, burrs, or nicks. (2) Check external covers and hinges for loosening or damage. (3) Check wiring for squeezing or damage. (4) Check power cord for insulation problems (conductor must not be exposed). (5) Check that power cord is properly connected. Warning : (1) Verify that the copier is properly grounded. If a problem is detected, establish a proper ground connection. (2) Connecting the ground lead to an improper point such as listed below results in a risk of explosion and electric shock. Unsuitable ground points: - Gas pipe - Lightning rod - Telephone line ground - Plastic water pipe or water pipe or faucet that has not been approved by authorities for grounding use
G PRECAUTIONS FOR ON-SITE SERVICE
Caution : (1) Before performing maintenance work, read all relevant documentation (service handbook, technical notices, etc.) and proceed according to the prescribed procedure, using only the prescribed tools. Do not carry out any adjustments not described in the documentation. (2) If the power cord is damaged, replace it only with the specified power cord. If the power cord insulation has been damaged and there are exposed sections, shortcircuits and overheating may occur, leading to a serious fire risk. (3) Do not route the power cord so that it can be stepped on or pinched. Otherwise overheating may occur, leading to a serious fire risk. (4) When disconnecting any cables, always grasp the connector and not the cable (especially in the case of AC and high-voltage leads). (5) Carefully remove all toner remnants from electrical parts, electrodes, etc. (6) Make sure that wiring cannot come into contact with sharp edges, burrs, or other pointed parts. (7) Double-check to make sure that all screws, components, wiring, connectors, etc. that were removed for maintenance have been reinstalled in the original location. (Pay special attention to forgotten connectors, pinched cables, forgotten screws, etc.) (8) When installation and preventive maintenance, verify that the power cord has been securely plugged into the AC outlet. Contact problems may lead to increased resistance, overheating, and the risk of fire. Warning : (1) Before disassembling or adjusting the optical unit or any parts that use a laser, make sure that the power cord has been disconnected.

Safety and Important Warning Items
(2) Do not remove the main cover of the write unit. Direct exposure of the eye to laser beams may lead to blindness. (3) Do not turn the copier on while the write unit is not installed in its normal position. (4) Danger of explosion if battery is incorrectly replaced, replace only with the same or equivalent recommended by the manufacturer. Discard used batteries according to the manufacture's instructions. Vorsicht : (4) Expiosionsgefahr dei unsachegemäßem Austausch der Battetie. Ersatz nur durch denselben oder einen vom. Hersteller empfohlenen gleichwertigen Typ. Entsorgung gebrauchter Batterien nach Angaben des Herstellers.
G HANDLING OF MATERIALS FOR SERVICING
Caution: Drum cleaner (alcohol-based) and roller cleaner (acetone- based) are highly flammable and must be handled with care. When using these materials for cleaning of copier parts, observe the following pre-cautions. (1) Disconnect the power cord from the AC outlet. (2) Use only a small amount of cleaner at a time and take care not to spill any liquid. If this happens, immediately wipe it off. (3) Perform cleaning only in an environment where sufficient ventilation is assured. Breathing large quantities of organic solvents can lead to discomfort. (4) Do not replace the cover or turn the unit on before any solvent remnants on the cleaned parts have fullyevaporated. Caution: Toner and developer are not harmful sub-stances, but care must be taken not to breathe excessive amounts or let the substances come into contact with eyes etc. If this happens, immediately rinse with eye wash and plenty of water, and consult a physician.
G MEASURES TO TAKE IN CASE OF AN ACCIDENT
(1) If an accident has occurred, the distributor who has been notified first must immediately take emergency measures to provide relief to affected persons and to prevent further damage. (2) If a report of a serious accident has been received from a customer, an onsite evaluation must be carried out quickly and Konica Corporation must be notified. (3) To determine the cause of the accident, conditions and materials must be recorded through direct on-site checks, in accordance with instructions issued by Konica Corporation.
G CONCLUSION
Safety of users and customer engineers has topmost priority, ranking even higher than operability. Safety depends on a appropriate maintenance work and is maintained by proper daily service work conducted by customer engineers. When performing service, each copier on the site must be tested for safety. The customer engineer must verify the safety of parts and ensure appropriate management of the equipment.
